Probability Distribution Function (PDF) for a Discrete Random Variable · Exercise 12
We know that for a probability distribution function to be discrete, it must have two characteristics. One is that the sum of the probabilities is one. What is the other characteristic?
Its source prints no answer for this problem, so there's nothing to check against.
